Description

Technical Field

[0001] The utility model relates to the field of active intake grilles, in particular to an occlusion structure for an external active intake grille. Background Technique

[0002] The external active intake grille is an advanced automotive design element that combines an intelligent control system with a dynamic adjustment function. It can automatically adjust the opening and closing degree of the intake grille according to the vehicle driving state and environmental conditions. The external active intake grille is an intake system installed at the front of the vehicle. It receives signals such as vehicle speed and engine temperature through an intelligent control unit (ECU) and automatically adjusts the opening and closing degree of the intake grille to optimize air circulation and engine performance. When the engine needs more intake air (such as during acceleration, climbing, etc.), the intake grille is fully opened to ensure sufficient air supply for the engine. When the engine temperature is relatively high or the vehicle speed is relatively fast, the intake grille is partially or fully closed to reduce the amount of air entering, reduce wind resistance and engine load, reduce unnecessary air resistance, reduce fuel consumption, and improve the fuel economy of the vehicle. When driving at high speed, closing the intake grille can reduce aerodynamic interference and improve the stability and controllability of the vehicle.

[0003] The existing EX1E active intake grille is an external active intake grille with strict requirements for appearance. When the blades are opened, it is easy to see the internal mechanical structure, which is very unsightly. Therefore, it is particularly important to design an occlusion structure for the external active intake grille. Summary of the Utility Model

[0025] An embodiment of the present utility model provides a shielding structure for an external active intake grille.

[0026] Such as Figure 1-8As shown, a shielding structure for an external active intake grille. The EX1E active intake grille is an external active intake grille, with dual motors 6 arranged on both sides. Only one side is shown in the figure. A main frame 1 is provided on the active intake grille. A protective shell is provided on the side of the main frame 1. The motor 6 is arranged inside the protective shell. A shielding box 7 is provided on the side of the protective shell. A transmission shaft 5 is arranged inside the shielding box 7. The transmission shaft 5 is connected to a connecting rod 4. Two empty frames are provided on the main frame 1, with upper blades 2 and lower blades 3 arranged inside the empty frames. Blade rotating shafts 8 are provided on the upper blades 2 and the lower blades 3. Blade rotating shaft extension plates 9 are provided on the blade rotating shafts 8. The blade rotating shaft extension plates 9 extend into the shielding box 9. The blade rotating shaft extension plates 9 are as Figure 7-8 shown. The blade extension plate 9 is provided with a hole at the contact point between the shielding box 7 and the main frame 1 and penetrates into the shielding box 7. A plug is provided at the top of the blade rotating shaft extension plate 9 that enters the shielding box 7.

[0027] As Figure 4 , as shown in Figures 7, 8, the transmission shaft 5 is provided with an arc-shaped notch. A connecting shaft is provided at the other end of the transmission shaft 5 and is connected to the motor 6. A circular raised block is provided on the connecting rod 4. The circular raised block is fixedly connected to the arc-shaped notch on the transmission shaft 5. A groove is provided on the connecting rod 4. The groove is fixedly connected to the plug at the top of the blade rotating shaft extension plate 9. The upper and lower ends of the connecting rod 4 are fixedly connected to the blade rotating shaft extension plates 9 of the upper blade 2 and the lower blade 3. During use, the motor 6 drives the transmission shaft 5 to rotate. The rotation of the transmission shaft 5 drives the connecting rod 4 connected thereto to swing. The swing of the connecting rod 4 drives the rotation of the blade rotating shaft extension plate 9. The up and down rotation of the blade rotating shaft extension plate 9 causes the blade rotating shaft 8 passing through the hole in the shielding box 7 to rotate around the axis in the hole. Since the blade rotating shaft 8 rotates, the upper blade 2 and the lower blade 3 rotate, realizing the opening and closing of the blades of the active intake grille. Since the reciprocating motion of the transmission shaft 5 up and down drives the reciprocating motion of the connecting rod 4, the opening and closing of the upper and lower blades in the active intake grille are realized.

[0028] The shielding box 7 is arranged against the side of the protective shell. A notch is provided on one side of the shielding box 7 and the protective shell for replacing parts of the detection box, such as Figure 7 shown. D represents the area where the set angle on the side of the shielding box 7 is 121.96°. This angle design increases the internal space of the shielding box 7, allowing the transmission shaft 5 and the connecting rod 4 to move better. The notch design also saves production materials, reduces costs, and is suitable for large-scale industrial production. At the same time, the strength of the shielding box 7 will not be affected because this notch design cannot be seen from the outside and does not affect the overall aesthetics. Also, various colors or patterns can be sprayed or printed on the outer surface of the shielding box 7 according to the user's preference.

[0029] For those skilled in the art, it is obvious that the present utility model is not limited to the details of the above-described exemplary embodiments, and the present utility model can be implemented in other specific forms without departing from the spirit or basic characteristics of the present utility model.
